We look at the division of 129957 by 81 
We want to divide 129957 by 81.

Step 1:
If we divide 1 by 81, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 81

Going ahead to step 2:
81 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 81

Moving on to step 3:
81 goes into 129 1 times with a remainder of 48.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 81 from 129, we get 48.
Grab the next digit (9) from the dividend, add it to 48, then carry on: 489 / 81

Going ahead to step 4:
81 can be fit into 489 6 times, resulting in a remainder of 3.
The next digit of our result is 6. 
Result so far: 16.0
Subtracting 486 from 489 leaves us with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 81

On to step 5:
When dividing 35 by 81, we get 0 with a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 160.0
Subtract 0 from 35 to get 35.
Bring next digit (7) of the dividend behind the 35 and repeat the process: 357 / 81

Let's proceed to step 6:
When dividing 357 by 81, we get 4 with a remainder of 33.
The number 4 becomes the next digit in our result. 
Result so far: 1604.0
Subtracting 324 from 357 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 7:
The number 81 fits into 330 4 times, leaving a remainder of 6.
The next digit of our result is 4. 
Result so far: 1604.4
Deduct 324 from 330 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
If we divide 60 by 81, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 1604.4
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
When dividing 600 by 81, we get 7 with a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 1604.407
If we subtract 567 from 600, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 10:
When dividing 330 by 81, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 1604.4074
Deduct 324 from 330 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
The number 81 fits into 60 0 times, leaving a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 1604.4074
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
600 divided by 81 is 7 with a remainder of 33.
The next digit of our result is 7. 
Result so far: 1604.407407
Subtract 567 from 600 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 13:
When dividing 330 by 81, we get 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 1604.4074074
The remainder is 6 after subtracting 324 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 14:
81 goes into 60 0 times with a remainder of 60.
The next digit of our result is 0. 
Result so far: 1604.4074074
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 1604.4074074, and the remainder is 6e-08.
